FIELD OF THE INVENTION

The present invention relates to an air conditioning system to be usedin a mobile home and more particularly to an air conditioning unit thatis adapted to deliver air to the interior of the mobile home through itsown built-in air distribution system. Provision is made duringconstruction of the mobile home to accommodate a mounting or adaptormeans that is located in the support structure of the mobile home andarranged to communicate with the air distribution system of the mobilehome. When properly located in the mounting means, the air deliveryoutlet of the air conditioning unit is aligned to deliver air to the airdistribution system of the mobile home.

The air conditioning unit when used is removably secured to the mountingmeans with its air outlet and inlet areas positioned to deliver air intothe mobile home air distribution system.

DESCRIPTION OF THE PRIOR ART

Traditionally, air conditioning units when used in mobile homes requirethe use of cumbersome, flexible duct work to connect the unit into theair distribution system of the mobile home. In many installations, theexposed flexible duct work would be installed in a manner that would beconsidered unsightly but, more importantly, they are delicate and aretherefore susceptible to physical damage.

U.S. Pat. No. 3,566,614-Imral provides a low-profile air conditioningunit that may be positioned under the mobile home. However, when the airconditioning unit, as taught in the above patent, is placed under themobile home, the unit must then be connected into the mobile home airdistribution system, which is an additional expense in both material andlabor. Furthermore, the unit must still be connected by either thecustomary light-weight, delicate, fexible ducting or the more expensiverigid, sheet-metal ducting which when used would have to be fabricatedand dimensioned for each installation requirements.

U.S. Pat. No. 3,712,078-Maynard provides a refrigeration unit includingtwo covers, one solid and the other having a plurality of opening thatare adapted to be used as inlet and outlet openings for circulating airfrom a removably mounted refrigeration unit into a refrigerator cabinet.The covers are dimensioned to be interchangeably secured to the bottomor top of the refrigeration unit, so that it may be positioned to supplyrefrigerated air upwardly when it is located in the bottom of thecabinet or downwardly when it is located above the cabinet.

U.S. Pat. No. 3,206,943-Rice et al shows a refrigeration unit arrangedor adapted to be removably positioned in the bottom of a refrigeratorcabinet. The refrigeration unit package is provided with rollers thatcooperatively engage a track positioned on the cabinet wall that permitslocating the refrigeration inlet and outlet openings into properalignment with appropriate air distribution flues in the refrigeratorcabinet.

While both of the above-mentioned U.S. Pats. Nos. 3,712,708 and3,206,943 provide removably arranged refrigeration units relative torefrigeration cabinets, it should be noted, however, that thecombination of both cabinet and refrigeration unit are necessary toprovide a functional product. In the present invention, an airconditioning unit is provided that is adapted to be installed in amobile home, that is a completely self-contained and usable productindependent of the air conditioning unit which may be provided as anaccessory.

U.S. Pat No. 2,525,869--Corhanidis discloses a refrigeration system thatis removably mounted on a railroad car. The refrigeration unit isreceived in rails that are mounted on a frame that in turn is insertedinto the floor of the chamber to be cooled. The frame has inlet andoutlet ports formed therein. The chamber to be cooled may be providedwith a conduit for receiving and distributing the cooled air. The abovepatent does not show nor teach the provision of a mounting means thatcan be used with a distribution system in a mobile home which mayinclude a plurality of zones partitioned or isolated from each other.The use of the system disclosed in U.S. Pat. No. 2,525,869 inconjunction with a mobile home would require a frame for each zone to beair conditioned.

The construction of the mobile home support structures relative to thepartitions separating the zones together with the various sizes of thezones would make the system disclosed in the above cited patentsimpractical.

The present invention provides a method and apparatus wherein an adaptorplate is installed in the mobile home during its construction and,optionally, at some later or subsequent time, an air conditioning unitthat is adapted to be removably received in the the adaptor means may besupplied and installed in the adaptor plate in alignment and cooperationwith the air distribution system of the mobile home.

SUMMARY OF THE INVENTION

By this invention, there is provided an air conditioning system for usein a mobile home and a method of adapting a mobile home for removablyreceiving an air conditioning unit. The mobile home includes thecustomary support structure which carries the mobile home livingquarters and an air distribution system providing an air inlet into theinterior of the living quarters of the mobile home.

A mounting means is secured to the mobile home support structure at thetime the mobile home is constructed. The mounting means is so arrangedand contructed that it is adapted to slidably receive the airconditioning unit at some later time. The mounting means furtherprovides air communication means from the air conditioning unit airdelivery outlet to the mobile home air distribution system and for theair returning from the interior of the mobile home to the airconditioning unit air-return inlet when the air conditioning unit isproperly located in the plate.

It is therefore an object of the invention to provide a system for airconditioning a mobile home and the method of adapting the mobile home toremovably receive a self-contained air conditioning unit.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to FIGS. 1 and 2 of the drawings, a mobile home 10 havingside walls 12 is supported on a base structure 14. The base structure 14includes a floor section 16 mounted on or carried on a support frame 18which may be mounted on a wheel assembly 20 for transporting the mobilehome from one location to another.

While the base structure 14 configurations may vary with manufacturersof mobile homes, two basic and accepted forms used by manufacturers ofmobile homes will herein be described in conjunction with the presentinvention. The support frame 18 usually includes parallel spaced mainsupport I-beams or members 19 arranged longitudinally with respect tothe mobile home 10. The beams 19 are spaced or located inwardly from theouter side walls 12 of the mobile home 10 to provide a support area 11.In order to provide adequate support for the entire width of the mobilehome 10 including the portion between the beam 19 and side walls 12,side support members 13 are spaced longitudinally and are secured to thebeams 19. The side support members 13 project laterally outwardly sothat the free ends are adjacent the outer edge of side walls 12 andsupport side beams 15 located directly under the outer walls 12.

In one type of mobile home construction, the floor section 16 includesfloor support member or joists 22, as shown in FIGS. 3, 4 and 5, thatare arranged parallel with the support beams 19 and side beam 15 in aspaced relationship across the width of the mobile home. The mobile homeis customarily provided with a forced air heating furnace (not shown)which distributes heated air to the various rooms, or zones 17, to beheated through an air distrubition system main duct 24. The duct 24 isarranged longitudinally extending usually substantially the full lengthof the mobile home, and may include air-delivery outlets 25 in each orselected ones of the zones 17 to be heated. In this arrangement, the airdistribution system main duct 24 used in conjunction with the heatingsystem of the mobile home 10 is arranged between floor joists 22, thatis between the floor 26 of the mobile home and the upper surface of thesupport member 19 or may be supported below them. In another type ofmobile home construction, and more specifically the floor supportsection 16, as shown in FIGS. 6, 7 and 8, the floor support joists ormembers 22A are arranged transverse to and are supported on the supportmember 19. The longitudinally positioned air distribution system duct 24in this configuration is arranged below the floor joist 22A and in theplane, or between the dimension defined by the upper and lower ends ofthe support members 19. In either floor section configuration thedistrubition duct 24 is arranged in the area between the I-beams 19.

In accordance with the present invention, an air conditioning unit 30(FIGS. 5, 8 and 9) is adapted to be used in conjunction with the mobilehome air distribution system duct 24. To this end, aligning and mountingmeans 27 are provided in either type of floor section 16 construction.The aligning means 27 include a mounting means or adaptor plate 28(FIGS. 5 and 8) secured to the underside of the floor section 16 duringthe manufacture of the mobile home. The air conditioning unit 30employed in the present system is capable of circulating conditioned airthrough the mobile home and is arranged to be removably received in theadaptor plate 28.

The plate 28 is conveniently located in the support area 11, as shown inFIGS. 3 and 6, between members 13 in one or more locations in the mobilehome, depending on the size of the mobile home, the number of zones tobe conditioned, and the preference of size and capacity of the airconditioning unit.

The back or rear edge of the plate 28 (FIGS. 5 and 8) is provided withan upwardly projecting flange 32 which is secured against the outer sideof support beam 15 below wall 12 of the floor section 16. The front orforward edge of the adaptor plate 28 is provided with a downwardlyextending flange 34 which includes a series of elongated slots oropenings 36. Secured in the slots 36 are angle or support brackets 38which may have their other ends secured to the floor support joist 22 or22A. The brackets 38 are similarly provided with a plurality of holeswhich, together with the slots 36, allow a great degree of vertical andlongitudinal flexibility of the forward end of plate 28 with respect tothe spacing and dimensions of the joist 22 or 22A.

Referring now to FIG. 9, the air conditioning unit 30 to be used inconjunction with the mobile home 10 and its distribution system duct 24is a self-contained unit arranged in a cabinet 31 and includes thecustomary refrigeration system having an evaporator section 42,condenser 43, compressor 44, power supply or control section 46, a motor48 for driving fan 50 arranged in an opening in a barrier 52. The fan 50moves air in through an opening 51 in the side wall of the cabinet 31and through the condenser 43 on the other side of the barrier 52 and outthrough louvers arranged in the rear wall of cabinet 31. The motor 48 isof the double-shaft type and also drives a blower 54 arranged in theother side of a barrier 56 which is the main barrier dividing thecabinet 31 into the customary indoor-outdoor sections. The blower 54draws air through a return inlet 58 arranged in the cover or upper wallof cabinet 31 through an appropriate filter 60 (FIG. 10), evaporator 42,and into a discharge chamber 61 which includes air discharge outlet 62arranged in the upper wall and an outlet 64 arranged in the forward wallrespectively of cabinet 31. As will be explained hereinafter, the choiceof outlets 62, 64 will be based on which type of floor construction 16the mobile home includes and the adaptor plate 28.

The air conditioning unit 30 used in conjunction with the presentembodiment of the present invention may be of the type that providesboth cooling and heating, in which event the mobile home heating furnacemay not be installed or used. In order to supply heated air to themobile home the air conditioning unit may be of the reverse cycle, heatpump type or alternately as shown in FIG. 9 a resistance heater 59 maybe arranged in the path of discharge air in the chamber 61. It should beunderstood that when the air conditioning unit provides both cooling andheating, a heating furnace may not be supplied and the air distributionduct 24 may be segmented depending on the number of air conditioningunits used and the number or locations of the zones. As will behereinafter explained in detail, the air conditioning unit 30 iscontrolled by a temperature responsive thermostat means 63 arrangedconveniently in one of the mobile home zones 17.

The aligning means 27 and more specifically the adaptor plate 28, usedin the floor section construction shown in FIGS. 6, 7 and 8, is providedwith an air-return opening 66 arranged, as will be hereinafterexplained, to communicate with the interior of the mobile homes and anair outlet 68. It will be noted that the opening 66, as will behereinafter explained in detail, aligns with opening 58 while opening 68aligns with opening 62 when the air conditioning unit is fully locatedin the adaptor plate 28. In this embodiment, the air conditioning outlet64 is not employed and is covered with an appropriate plate or cover 70.

To properly insure the alignment of the openings 58 with 66 and opening62 with 68, the adaptor plate 28 is provided with a depending track orsupport means 72 projecting downwardly along the parallel side walls ofthe plate 28. The track 72 is provided with a raceway 74 formed toreceive a guide member 76 (FIGS. 5, 8 and 9) projecting from the upperside edges of the upper wall of the air conditioning unit cabinet 31.The raceway 74 is formed so that it inclines upwardly from the flange 32end of the plate 28. The guide member 76 has a downwardly projecting cammember 78 formed on its trailing edge.

In operation, that is during the insertion of the air conditioning unitguide member 76 into the raceway 74 of the adaptor plate 28, the leadingor forward edge of the guide member 76 rides upwardly in the raceway 74toward the underside of the plate 28 with the cam member 78 engaging theopen rear end of the raceway 74 just prior to the complete insertion ofthe air conditioning unit 30. During the last portion of the insertionprocess, the cam member 78 causes the rear or trailing end of the airconditioner to be raised as it is completely inserted into the raceway74 so that the top wall of the cabinet 31 is parallel to and against theplate 28 with the appropriate openings 58, 66 and 62, engaged in asealed air transfer position.

In order for the blower 54 to draw air from the interior of the mobilehome, means are provided to connect air-return openings 58 and 66 withan opening 82 in the floor 26 of the mobile home. Accordingly, as seenin FIGS. 5, 8 and 10 the air-return openings 66 and 58 are aligned by asuitable ducting 80 which defines an air-return passageway or opening 81in the floor section 16. The opening 82 may be provided with anappropriate removably arranged grille 84.

By the present invention, the aligning means 27 also includes aircommunication means for delivering air from the aligned outlets 62, 68to the distribution system main duct 24. To this end (FIG. 8), duringconstruction of the mobile home the outlet 68 of plate 28 is connectedthrough an air conduit or passageway means 86 to an opening 88 on theupper wall of the air distribution system main duct 24. It should benoted that in this type of mobile home construction the air conduit 86is located between transversely arranged floor joists 22A and across thetop of support member 19. The duct 80 and conduit 86 like the plate 28are installed during the construction of the mobile home. As can readilybe understood the conduit 86 provides a means for aligning the opening68 in plate 28 of aligning means 27 and more specifically, the airconditioning air outlet 62 with the distribution system duct 24 so thatcooled air from the air conditioner may be delivered through duct 24into selected zones or zones to be cooled, while the duct 81 providesmeans for aligning the air conditioner air return inlet with anappropriately located opening 82 in the selected zone to complete therecirculation of air through the selected mobile home zone. It should benoted that during construction of the mobile homee appropriate removablecover members (not shown) are arranged over the openings 66 and 68 inplate 28 to prevent leakage of air from the mobile home distributionsystem duct 24 and interior of the mobile home during normal operationof the heating system in the event an air conditioning unit is notinstalled. In the event an air conditioning unit is required for themobile home, the covers are removed from openings 66, 68 and the airconditioning unit 30 is inserted on the tracks 72 at that time.

The aligning means 27, and more specifically the adaptor plate 28,employed in the floor construction of the mobile home 10 shown in FIGS.3, 4 and 5, provides means for connecting the air outlet 64 of the airconditioner unit 30 into communication with the air distribution duct24. It should be apparent that the longitudinal arrangement of joists 22in this type of construction precludes the positioning of a conduit forconnecting the air conditioning unit with the mobile home airdistribution system across the top of the beam 19. Accordingly the aircommunication means from the air conditioner air delivery outlet to theair distribution system duct 24 is arranged to extend across the bottomof support member 19.

To this end, the aligning means 27 provides a bulkhead or plate 90 whichincludes an opening 92 secured to the flange 34. The plate 90 extendsdownwardly so that the opening 92 is located below the lower edge ofbeam 19. The opening 92 is adjusted into horizontal alignment withopening 64 by positioning the plate 90 in the slots 36 of flange 34. Thevertical adjustment to align openings 92, 64 is accomplished by thepositioning of brackets 38 relative to the cross members 93 secured tothe joist 22.

Further, in this type mobile home construction, communication betweenthe air conditioning unit 30 and duct 24 is effected by an air conduitmeans 94. The conduit 94 extends from the opening 92 across the bottomedge of beam 19 and then upwardly to an opening 96 in the mobile homeair distribution duct 24. Alternatively the opening 64 in the cabinet 31may be located in the side wall and the plate 90 arranged adjacent theside wall with duct 94 extending across the bottom of beam 19 ashereinbefore described.

Means are provided to support and position the duct 94 on the beam 19 sothat duct 94 is axially aligned with opening 92 on the plate 90.Accordingly, the duct 94 rests and is supported on the bottom wallportion of a U-shaped sleeve member 100. The upper ends of the side wallportions 101 of the sleeve 100 are provided with outwardly projectingflanges 102. The sleeve 100 is secured to the beam 19 by a pair ofclamps 104 that are secured to each of the flanges 102 and areappropriately shaped to engage the lower oppositely projecting legportion of the I-beam 19. This clamping arrangement provideslongitudinal adjustment along the I-beam 19 while the placement of theclamps 104 in appropriate holes arranged in the flanges 102 provideshorizontal axial adjustment relative to opening 92. The sleeve 100 issecured in appropriately selected openings in a vertically arrangedflange 106 formed in the plate 90 to support the aligned conduit 94between the bottom wall of sleeve member 100 and the beam 19. As canreadily be understood the conduit 94 provides a means for aligning theopening 92 in plate 90 of the aligning means 27 and more specificallythe air conditioning air outlet 64 with the distribution system duct 24.

By the present mobile home air conditioning system, access is providedto certain essential electrical control and operating components of theair conditioning system from the interior of the mobile home.Accordingly, various service functions may be performed withoutnecessitating the removal of the air conditioner from its adaptor plate.

Referring now to FIGS. 9 and 10, it will be seen that access to thefilter 60, control section 46, compressor 44, and a control box 117, isprovided from the interior of the mobile home and more specificallythrough the air-return opening 82. To this end the opening 58 isdimensioned to extend beyond the evaporator side of barrier 56 to exposecompressor 44 and control section 46.

A power cord, including a high-voltage plug 107 which is connected tothe mobile home power supply (not shown), and a low-voltage cord,including a low-voltage plug 108 connected to a temperature controlmeans or thermostat (not shown), are conveniently arranged in anelectric component or storage area 109 located in air-return passageway81 below the grille 84. The area 109 is provided with a protective cover110 which is accessible with the removal of grille 84. The plug area 109is arranged over the control section 46 when the air conditioner isfully positioned in the plate 28. The bottom wall of the area 109 isprovided with openings 111 which align with high-voltage receptacle 112and low-voltage receptable 113 mounted in the control section 46. Toelectrically connect the air conditioner 30 to the power source and tothe appropriate temperature control means of the mobile home, cover 110is removed or rotated to its open position and plugs 107, 108 areinserted through openings 111 and into receptacles 112 and 113respectively.

As can easily be understood that with the electrical connection made andplugs 107, 108 projecting through opening 111, a mechanical interlock isprovided in that the air conditioner cannot be removed until plugs 107,108 are removed from receptacles 112 and 113. However, to increase theintegrity of the interlock and to satisfy certain codes, a mechanicalinterlock means is provided. To this end, a pin 114 attached to thehigh-voltage plug 107 is dimensioned to extend through an opening 115 ofthe bottom wall of area 109. At the time plug 107 is inserted intoreceptacle 112, pin 114 is arranged to be received in an opening 116 insection 46, thereby providing a mechanical interlock between theremovably arranged air conditioning unit 30 and the plate 28 secured tothe mobile home 10. It should be understood, however, that while the pin114 is attached to the plug 107 it may be associated with plug 108, oralternatively, plugs 107, 108 may possibly be combined, with the pin 114being associated with the combined plug. The above arrangement, however,does provide an interlock when the air conditioner is electricallyconnected to the power source that is effective in preventing theremoval of the air conditioner 30 from the plate 28.

Also accessible as hereinbefore mentioned through the air-returnpassageway 82 is the control box 117 which is located in the evaporatorside of barrier 56. The control box 117 may contain circuit terminalcheck points and other electrical components that may require periodicinspection and is provided with a protective cover 118.

It is apparent from the foregoing that many of the service functionsthat may be necessary regarding the maintenance of air conditioner 30including inspection of filter 60 may be carried out from the inside ofthe mobile home through the air-return passageway 81 and, morespecifically, without removing the air conditioner 30 from the plate 28.

Referring to FIGS. 3, 6 and 9, the insertion of low-voltage plug 108into receptacle 113 completes a low voltage circuit to the thermostat 63that is effective to control the operation of the air conditioning tomaintain a preselected temperature in the zone or zones 17. In the eventmore than one air conditioning unit 30 is employed in the mobile home 10a separate thermostat 63 may be provided for each of the units or acentral control may be utilized. The specific arrangement of thetemperature control may vary with each installation.

In summary it should be apparent from the foregoing description that anair conditioning system and method are provided for air conditioning amobile home that includes installing a mounting means duringconstruction of the mobile home for adapting the mobile home toremovably receive a self-contained air conditioning unit. The mountingmeans further includes air communication means for connecting the airconditioner in air communication with the distribution system duct ofthe mobile home.
